Benefits of technology

The present invention provides a method for automatically testing a dedicated communication line to locate failures in a communication line management system. The method eliminates the need for manual testing, reduces the time taken to locate a failure, and improves the efficiency of the system. The method uses a database to organize information on test points, test history, and test point search priorities, and a computer program to perform the testing and recording of results. The technical effects of the invention include improved efficiency in identifying and repairing failures in dedicated communication lines.

Problems solved by technology

This method is not desirable in the present environment requiring a great number of high-speed dedicated communication lines especially for Internet.

Embodiment Construction

Referring to FIG. 1, a dedicated communication line management system includes terminal equipments (TEs) 101, network elements (NEs) 102, remote test units (RTUs) 103, central control unit 105, X.25 or LAN 104 connecting RTUs with the central control unit 105, database 106, and operating terminal equipments 108 for the central control unit 105.

A dedicated communication line consists of TEs 101 connected with the dedicated communication network. The dedicated communication network comprises various NEs 102 such as MDF (Main Distribution Frame), PCM (Pulse Code Modulation), DCS (Digital Cross-connect System), etc. The RTU 103 is connected to NE 102 to monitor a dedicated communication line, and to transfer and split signals, and to perform loop-back test when there is a failure notice. It is controlled by the central control unit through X.25 packet network or LAN 104. The central control unit 105, database 106 and operating terminal equipments 108 are connected with the data communic...

Abstract

A method for locating a failure of a communication line according to self-adjusted priorities of the test points in the order of high failure probability in a communication line management system, includes the steps of organizing the test points, information on the test history of the test points, and test point search priorities (TSPs) representing the priorities of the test points in the order of high failure probability into a test database, searching the test database to determine the testing order of the test points according to the TSPs, testing the test points in the testing order to locate the failure, and revising the values of the data fields of the TSPs according to the test results and the location of the failure.

Description

The present invention relates to a method for locating a failure of a communication line in a communication line management system, and more particularly to a method for testing a communication line according to self-adjusted test point priorities in a communication line management system, which automatically determines the order of testing the points for locating a failure.PRIOR ART OF THE INVENTIONConventionally, the dedicated communication network provides dedicated communication lines with remote test units (RTUs) respectively connected to the equipments of their telephone office to test their failures. Hence, when the telephone office receives a trouble report from a subscriber of a dedicated communication line, an operator tests the RTUs connected with the dedicated line to locate a failure, and notifies an engineer in charge to repair it.Hence, such conventional test method depends on the experience, capability and arbitrary judgment of the operator to locate the failure, so ...
